Cox Orange Pippin Apple trees

Apple    North Idaho

I have planted 3 Cox Orange Pippin Apple trees in my yard over the past 13 years. 1 is 3 years old, one is 8 and one is 12 years old. All were bought from different plant nurseries, and planted NOT near each other, but within a variety of cherry, plum, apple, asian and american pears, and assorted pluots/plumcots. All 3 of my Cox pippins have all sorts of moss growing on them, but it has not affected the fruits, leaves or any other aspect of the tree. They are healthy, viable plants, but when you walk thru my orchard, these 3 are all the same with the moss. None of the other apples, or other fruits have the moss on them.. Who can tell me what causes this for THIS particular tree, and has anyone else noticed the same on their Cox Orange Pippins. Thanks for the help, this is mostly for my curiousity...

To decide between Moss and something else like Lichen a picture is needed. Below is a picture of Lichen on a Cox Orange Pippin Apple

Lichen is a composite organism (two things living together); a fungus and an algae. They are fine and are not harming your tree.

if it is Moss (need picture) then it will be taking resources from your tree

Yep, great job with the picture, that is what I have..I knew it wasn't harming the tree, but wonder why it grows ONLY on the Cox Orange Pippin and not on the apple trees surrounding it...It just seems so odd, and I know that Cox trees are quite an heirloom tree, so, thank you very much for this picture and info.

Lichen are very sensitive to the environment. It is a sign of good clean air (low ozone, no smoke) when you see them growing on buildings.
Because of this sensitivity I suspect the other trees dont have naturally occurring chemicals in their bark that does not allow the Lichen to grow.

Can you please add an image to your question so I, and others, can see/check that it is Lichen. Will be useful for all. Thanks
